Installing two PA speakers with a single Loudmouth
™
receiver
Many locations may require the installation of two speakers with a single Loudmouth
™
receiver. Two speakers are used when:
You can connect 2
speakers to a single
Loudmouth
™
receiver
using an RCA phono
type Y-connector.
(i.e. Radio Shack
Catalog # 274-881 )
• Coverage is required over a large area.
• Large obstructions limit the effective range of a single speaker.
• A wall separates two coverage areas.
• The ambient noise level is low and individual speaker volume must be reduced
(i.e. Hospital).
• The calling radio is in the area where the speakers are located and speaker
volume must be reduced to prevent feedback.
In some installations a single Loudmouth
™
receiver can be used to drive two
speakers, while others will require a separate receiver for each speaker.
To cover a large area, or an area with large obstructions, place 2 speakers
back-to-back in a central location.
• The speakers should be mounted as high as possible and pointing away from each other.
• The 2 speakers can be driven by a single Loudmouth
™
receiver.
• Volume level may be reduced compared to a single speaker, making the system less susceptible to
feedback.
Use 2 Speakers to reduce volume level
Surprisingly, the use of 2 speakers powered by a single
Loudmouth
™
receiver can allow you to reduce the volume
level in a quiet environment.
By covering an area with 2 centrally located speakers,
installed back-to-back, the volume level can be cut in half.
